Though survival items may vary based on personal wants and needs, below are a standard few, provided by the BlackEnterprise.com team, which can serve as a baseline to build from.

1. Phone ChargerHave you ever been caught in the middle of the work day with a dead cellphone? The thought alone is terrifying.
